Answer:
Option: A is the correct answer.
The measure of ∠ABC is 60°.
Step-by-step explanation:
From the intersecting chord theorem we have:
m∠ABC is the mean of the sum of the length of arc AC and length of arc DE.
Also it could be understood from the figure attached to the answer.
Hence, we have:
m∠ABC=(measure arc AC+measure arc DE)/2
⇒ m∠ABC=(45°+75°)/2
⇒ m∠ABC=120°/2
⇒ m∠ABC=60°
Hence, the measure of ∠ABC is:
60°

Answer: Hence, the 95% confidence interval for the mean is (1.2004, 1.2396).
Step-by-step explanation:
Since we have given that
Mean = μ = 1.20 pounds
n= 36
We need to find the 95% confidence interval for the mean.
So, z = 1.96
So, confidence interval would be
Hence, the 95% confidence interval for the mean is (1.2004, 1.2396).
